STOVE.

Specification ci Letters Patent No. 25,596, dated September 27, 1859.

To all whom fit may concern.:

Be it known that we, C. L. VHITNEY and SAMUEL REED, both of Geneseo, in the county of Henry and State of Illinois, have invented a new and Improved Stove; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure l, represents a vertical longitudinal section taken through the center of the stove, when the same is arranged for burning coal. Fig. 2, shows the manner of regulating the degree of heat in the oven and also tlfree pipes, the two outer ones being air flues, while the middle one is filled with clay as hereinafter set forth, the section being taken through red lines ai, of Fig. l. Fig. 8, is a plan showing the interior of fire chamber and lower flues, the top of the stove being removed as indicated by red lines y, y, of Fig. l. Fig. 4:, is a section taken through the red lines e, e, of Fig. l. Fig. 5, is a perspective view of the grate, etc., used when burning wood.

The nat-ure of our invention consists in the arrangement of flues and flue spaces so that the hot air is carried from the tire chamber under a deilecting plate and passed up through pipes arranged on each side of the front of the oven and over the oven and down thro-ugh similar pipes arranged in rear of the oven and thence out into the smoke pipe, and in the manner of attaining a regular increased draft in its passage through the stove; second, in the arrangement of pipes of clay or other similar substance within the oven and between the flue pipes in order to abstract and to retain the heat, and give it out slowly into the oven during the operation of baking, as hereinafter described.

By reference to Fig. l, A, shows the fire chamber, B, theoven, C, flue space below the oven. The lire chamber has arranged below the level of the hearth of the stove, a perforated plate o, which can be moved back and forth,-this operation sifts the ashes (when coal is used) down into a drawpan a, which can be readily removed and emptied of its contents, while the cinders and unburned coal is removed from the plate Z), for further use. Above this plate b, is a rack c, which is raised a suitable height above the hearth of the stove to admit a free draft, and upon this rests two plates (Z, CZ, each having an annular collar into which fits the bottom of conical lire pots D. These are held down to the plates and kept in position by hooks e, one on each side of the pots,- but previously to putting the pots on the plates circular rolling grates f, are laid over the holes in plates cl, the axles of which pass out under the rack so that the grate bars can be easily rotated, for emptying the fire pots of their contents. The sides of the pots D, are separated allowing a free circulation of air around them so that the side plates or front doors of the stove are not easily burned out by the action of the heat from the pots. These pots can be easily removed when either hot or cold so that one may be used and it placed directly under the boiler hole and thus, an economy of fuel.

Above the lire pots D, in the fire guard or back plate E, of the fire chamber are openings g, through which the heat passes, where it comes in contact with a curved deflecting plate F, curved so as to direct the hot air down toward the bottom plate G, and so diffuse it throughout the Hue space C. From this compartment C, are four pipes H, H, one in each corner of the oven B, which communica-te with a flue space directly over the oven, so that when the graduated damper J, is entirely closed down upon rest h, the heated air all passes up through the front pipes H, over the top of the oven and thence down the rear pipes and is finally carried 0E through smoke flue K, in the rear of the stove, and by slightly opening the damper J, and resting it upon stop pins z', a portion of the heated air escapes directly to the smoke flue, and by this means the heat passing into the oven is in a great measure regulated. Between the pipes H, in front and rear of the oven, are arranged pipes L, of clay, or other substance having the properties of absorbing heat and gradually giving it off; these pipes receive a great portion of the heat radiated from the pipes H, and gradually impart it to the oven, thus equalizing and diffusing the heat into the oven. On the side of the rear pipes H, is arranged two self-regulating dampers (seen in Fig. 2) which are operated so as to open and close the apertures K, by the expansion and contraction of rods Z, Z,-these are connected with a vertical slide mi, having a thumb screw n, which is raised or lowered, thus shortening the sweep of the rods Z, Z, so that a slight variation of teinperature in the oven Will effect the opening or closing of the dampers over the holes K,

and keep up a constant equality of temperature in the oven.

The escape of the smoke and gases through smokepipe K, is regulated by what may be called a governor. This is constructed with a cylinder N, having a draft hole communicating with chamber C; in this cylinder is pivoted a cylinder O, With its edge curved obliquely to the base so that by turning this inner cylinder the draft hole may be entirely closed or only partly closed. A cap p, is fixed to the bottom of the inner cylinder O, covering a false bottom and in the bottom of cylinder N, is a similar opening. Now by turning the cylinder O, With lever s, the opening in the bottom of the cylinder Will begin to close While the opening communicating' With the stove or flue chamber Will begin to open so that when the hole is half open the damper is half closed. The cap p, prevents the cold air rushing in at the bottom of the cylinder and the smoke and gas from the stove meeting each other and causes them to pass in opposite directions. The

cap performs another important function in preventing ashes or lire falling out when the cold air iue is opened.

The general arrangement of this stove is complete as regards economy of heat and fuel; and the convenience of cleaning out accumulated soot or ashes, While by removing the fire pots, Which can be readily done, and sliding into the fire Chamber, the box as represented by Fig. 5, the stove is converted into a Wood burning stove With all the facilities attending the same.

What We claim as new and desire to secure by Letters Patent, is,

l. The arrangement of deiiecting plate F, Chamber C, graduating damper J, and fine pipes H, H, in the four corners of the oven, all in combination for the purposes herein set forth.

2. And in combination with this We claim the use of pipes of clay or other similar material When the same are arranged in the manner and for the purposes above specified.
